My girl is 37lbs and 38in. Planning on keeping her rear facing until she’s maxes out the 40lbs or 40in of her seats rear face standard.
My boy is 29 pounds and 37 inches. We will turn him at 3 only because we have another baby coming in July and my car is tiny and we can't have a rear facing seat behind the driver.
My June girl is 37 inches tall and still rearfacing. My 5 year old who is 46 inches just asked to go back to rearfacing in fact. The fact that she still likes to rearface makes me convinced rearfacing is definitely more comfortable for kids than we assume.
My son is 35 pounds and has been front facing since he turned 2.
Front facing
My son has been FF since 2 . He couldn't ride backward as it made him car sick. I think with the right car seat FF is fine.
My daughter is 32lbs and 37in and we still rear face. Plan to do so till she’s 4-5 years old.
